|The development of blank verse may be the result of Renaissance poets imitating classical Latin and Greek poetry where meter was a feature, but rhyme was not. It was introduced into English poetry by Henry Howard, Earl of Surrey. Blank verse is written in iambic pentameter, and the lines may exhibit enjambment, or they may be stop-ended. The structure of blank verse differs from that of rhymed verse. Poems written in blank verse are often divided into "verse paragraphs" of varying lengths, as distinct from stanzas, which usually have regular lengths and are defined by their rhyme scheme and metrical pattern.
